Abstract

1. UN PROCEDIMIENTO PARA PRODUCIR UN POLIMERO ARO- MATICO DE MONOVINILIDENO QUE TIENE UN PESO MOLECU- LAR (Mw) MAYOR QUE 275.000, CARACTERIZADO PORQUE COMPRENDE UN MONOMERO AROMATICO DE MONOVINILIDENO, EN PRESENCIA DE: (A) DE 10 A 2,000 ppm EN PESO DE POR LO MENOS UN INICIADOR DE POLIMERIZACION DE RAMIFICACION, GE- NERADOR DE RADICAL LIBRE; Y (B) DE 10 A 2,000 ppm DE UNO O MAS AGENTES DE RE- DUCCION DE GAL ORGANICOS, SELECCIONADOS DEL GRUPO QUE CONSISTE DE: (1) MARCAPTANOS, TERPENOS, HALOGENOCARBONOS Y HALOGENOHIDROCARBUROS; TENIENDO DICHO AGENTE HASTA 20 ATOMOS DE CARBONO; (2) UN DESTILADO RECUPERADO DEL PROCESO DE DESVO- LATILIZACION EN REACCION (RECIRCULACION); Y (3) MEZCLA DE (1) Y (2).1. A PROCEDURE TO PRODUCE AROMATIC MONOVINILIDENO POLYMER THAT HAS A MOLECULAR WEIGHT (Mw) GREATER THAN 275,000, CHARACTERIZED BECAUSE IT INCLUDES AN AROMATIC MONOVINILIDENO MONOMER, IN THE PRESENCE OF: (A) FROM 10 TO 2,000 ppm OF AT LEAST ONE RAMIFICATION POLYMERIZATION INITIATOR, GENERATOR OF FREE RADICAL; AND (B) FROM 10 TO 2,000 ppm OF ONE OR MORE ORGANIC GAL REDUCTION AGENTS, SELECTED FROM THE GROUP THAT CONSISTS OF: (1) MARCAPTANS, TERPENES, HALOGENOCARBONS AND HALOGENOHIDROCARBONS; HAVING SAID AGENT UP TO 20 CARBON ATOMS; (2) A DISTILLATE RECOVERED FROM THE PROCESS OF DEVOILIZATION IN REACTION (RECIRCULATION); AND (3) MIXTURE OF (1) AND (2).
